The idea came up on the call yesterday that it might well be worthwhile to have another development meeting mid/late summer. Of particular interest is design discussions about asynchronous progress.

The next MPI Forum meeting runs 1pm June 4 (Tue) through noon June 7 (Fri). Assuming that several/many of us may be attending that meeting any way, we could try to schedule around that (e.g., morning of Tuesday and/or afternoon of Friday).

The next MPI Forum meeting is in Madrid (11-13 Sep), followed by EuroMPI (15-18 Sep). That doesn't seem like a good opportunity for an Open MPI dev meeting.
